Title: Image binarizing processor
Inventor: NOZOE JUNJI
IPC: H04N1/40
Filed: 1992-01-17
Abstract: PURPOSE:To provide an image binarizing processor which can easily obtain a binary image to exactly display a photographing subject with no noise, no blur, etc. CONSTITUTION:A luminance-frequency calculating means B calculates the coordinate marks for each stage of luminance based on the multi-level image information on an area to be measured and stored in a multi-level image information storage means A. Then a histogram information converting means C converts a coordinate system consisting of the luminance stage and the frequency into the histogram information equivalent to a binarized screen where the frequency calculated by the means B is defined as a boundary. A smoothing processing means D secures the histogram information having the smoothed local recesses and projections for display of an image. Then a contraction processing means E secures the contracted histogram information having the separated top parts for display of an image. A threshold value selecting means F defines the luminance value which separates the top parts as the threshold value. Then a binarization processing means G binarizes the multi-level image information based on the threshold value.

Title: Display device
Inventor: NAMIUE TAKESHI
IPC: G09G3/02
Filed: 1990-02-06
Abstract: PURPOSE:To display an image of high resolution, to maintain uniform lightness and sufficient brightness extending over the whole screen and to easily make the screen large and flat at the same time by using a laser beam and finely controlling the laser beam. CONSTITUTION:An image signal received by a signal cable 9 is converted to an electric signal by a signal conversion device 5. Based on the electric signal, the ON/OFF of the generation of the laser beam is controlled by the controller 2 of a light source 1. Then, a reflecting plate driving device 4 is operated by synchronizing it with the electric signal with the aid of a synchronization controller 6. Besides, the angle of a reflecting plate 3 is smoothly moved top and bottom and left and right so as to make the laser beam emitted from the light source 1 of the laser beam scan one screen. By repeating such an action, an image is displayed on a fluorescent surface 7. Thus, the screen is made flat and large and high resolution is imparted to the screen. Besides, the display with uniform lightness is realized and the screen is easily made large and flat.

Title: Frequency multiplier for rectangular wave
Inventor: TANIGUCHI AKIRA
IPC: H03K5/00
Filed: 1979-03-12
Abstract: PURPOSE:To make it possible to generate a doubled signal synchronizing with a rectangular wave, by generating a sawtooth wave signal which is cleared every time the rectangular wave rises or falls. CONSTITUTION:Rectangular wave A supplied to input terminal 20 is sent to one- shot multivibrator 22, which outputs signal B giving one shot at every rise and fall, thereby outputting pulses twice the input signal. Then, an integral arithmetic part, composed of resistance R4, capacitor C4 and operational amplifier 25, integrates reference voltage Vref and is controlled by switching element S1 to generate saw- tooth wave signal C cleared every time the one-shot pulse is generated. This signal C is level-shifted by a differentiating circuit into signal D, which is then supplied to comparing operational amplification circuit 26. Consequently, rectangular wave signal E of a double frequency can be extracted which synchronizes with the rise and fall of the input signal.

Title: Parameter data inverter
Inventor: POORU ESU BURIIDORABU
IPC: G10L19/06
Filed: 1980-03-05
Abstract: A speech synthesis circuit is provided with a variable frame length data converter and the speech synthesizer is preferably integrated on an integrated circuit chips. The variable frame length data converter reduces the amount of data required to synthesizer human speech at a given quality level. Preferably, a full frame of data includes, a pitch parameter, an energy parameter, a repeat bit and a plurality of speech coefficients. Each parameter or coefficient has a preselected length, but each frame has a variable number of parameters or coefficients associated therewith. The parameters and coefficients are encoded and a particular code of the pitch parameter indicates that the speech is to be unvoiced. An unvoiced frame includes fewer coefficients that a voiced frame and the converter detects this particular pitch parameter and automatically sets the unsent coefficients to zero. The converter also detects the state of the repeat bit for controlling the synthesizing to use the coefficients received during the previous frame as the coefficient to be used to generate speech in response to the present frame. In this embodiment, when the repeat bit comes up, new pitch and energy parameters are inputted therewith. Further, the converters preferably detects particular codes in the energy parameter for determining when a pause occurs or when the last frame of data has been sent.

Title: Alternator
Inventor: HOTTA TOSHIAKI
IPC: H02K1/24
Filed: 1990-02-07
Abstract: PURPOSE:To increase output without enlarging the size of an alternator by increasing the cross sectional area of a pole core hook part at high flux density region thereby increasing the flux density. CONSTITUTION:Upon power supply to a field winding 3, flux is induced and passes through the hook parts 103, 203 of pole cores 1, 2. Flux density increases gradually from the end faces 112, 212 on the rotational direction side of the hook parts 103, 203 of the pole cores 1, 2 toward the end faces 113, 213 of the hook parts on the opposite side in the rotational direction. When the cross sectional area of the hook parts 103, 203 at high flux density region is increased, magnetic resistance is decreased and more flux can be fed through the pole cores 1, 2. Since more flux can be passed through an armature winding 6, output of an alternator can be increased by simply modifying the profile at the hook parts 103, 203 of the pole cores 1, 2.

Title: Serial-parallel converter
Inventor: NAKAYAMA SHUNICHI
IPC: H03M9/00
Filed: 1986-02-12
Abstract: PURPOSE:To decrease the circuit scale and the limitation relating to the write/ read timing by inputting an input serial signal sequentially to n-set of elastic stores connected in parallel, writting the signal in the same address and reading the storage content of the same address simultaneously from the n-set of the elastic stores at readout. CONSTITUTION:The input serial signal 1 is inputted directly to eight set of elastic stores 8-1-8-8 and written one by one bit each in the same address sequentially as shown in figures B-1-B-8 by the control of a control circuit 10. The same address of the eight elastic stores 8-1-8-8 under the control of the control circuit 10 at the same time is accessed to obtain an 8-bit parallel signal 7 as shown in figure C in the tentative storage of a latch circuit 11. Thus, the scale of circuit is reduced remarkably and the limit of the read/write timing is not avoided so long as the same address is not accessed because of the use of the elastic stores.

Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To obtain superior visual field selectivity by stacking one visual field selective layer and one base material layer and forming many directional crazes penetrating the visual field selective layer to its overall thickness. SOLUTION: The visual field selective film 1 consists of at least one visual field selective layer 2 and at least one base material layer 3 and has many crazes 4 optionally containing light absorptive substance or light scattering substance in the visual field selective layer 2. A body 5 behind the visual field selective film 1 can, therefore, be viewed by an observer 6, but can not be viewed by an observer 7 since it is shielded by the crazes 4. Namely, the film has the visual field selectivity that the body, etc., behind it can be viewed in the certain direction, but can not be viewed in other directions. The crazes 4 of the visual field selective film 1 have nearly the same width (distance between both walls of cracks of the crazes 3) along the thickness of the visual field selective layer 2.
